Two alternative healers who allegedly treat clients using Amazonian frog poison have been banned amid fears the therapy could be putting the public at risk.

There have been growing concerns about the practice, known as kambo, which involves burning the skin with a hot stick and then placing a poisonous secretion harvested from the skin of the giant green monkey frog on to the wounds.

Some kambo practitioners claim the poison is a strong natural anti-inflammatory, antibiotic and anaesthetic that detoxes the liver and intestines, and improves the immune system.

But it is known to induce pain, dizziness, shaking, swelling, fainting and severe vomiting.
